  Discovery of selective 2,4-diaminoquinazoline toll-like receptor 7 (TLR 7) agonists

  摘要：

  The discovery of a novel series of highly potent quinazoline TLR 7/8 agonists is described. The synthesis and structure-activity relationship is presented. Structural requirements and optimization of this series toward TLR 7 selectivity afforded the potent agonist 48. Pharmacokinetic and pharmacodynamic studies highlighted 48 as an orally available endogenous interferon (IFN-alpha) inducer in mice. (C) 2018 Elsevier Ltd. All rights reserved.
